Application filed November ll, 1903. Serial No. 180.729.

5 of Nebraska, have invented'an.Improvement in End-Thrust-Resisting Means for Bearings, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention has for its object a novel construction of means for resisting end thrust in bearings, especially bearings such as shown in United States Patent No. 713,058, ofranted November 11, 1902, my invention being also, it will be understood, a plicable to any form of bearing wherein it is esired to resist successfully the wear and shock due to end thrust in opposite directions;

In the patent referred to a series vof balls in a ball-race at one side of an end-thrust ring contact with a ring or track at the end ofthe hub or box.

In another a plication iiled concurrently with this, Seria No. 180,727, I have shown an end-thrust washer inter osed between two tracks detached Jfrom t e axle, one of which tracks also serves as a cagelcontroller, said washer having antiriction devices. at both sides; but` herein I have 'sustained through the axle two end-thrust washers each having at one face antifriction devices that contact with opposite sides of a track at the end of the hub or box, said track being shown as entering a pocket in an extension of the hub or box and as restrained against` rncvement longitudinally of the axis of :the ax e. Y

rihe drawingshows in section a suhcient portion of a hub or box and axlewith my im- Erovements added to enable my invention to e understood.. y 1 In the drawing, the axle B; having an enlarged portion B', on which'in practice will rest and roll usual bearing-rollers; held in cagnes, as represented in said patent, andthe hu or box B2 are and may be all as fully de# scribed in said patent. Herein the axle has a tenon C provided with a screw-thread, and

inner end of the screw-thread the axle has a reduced portion or neck 3.' The 'end of the hub orbox is shown as having a projection B3, represented as threaded "externally, on 'which is screwed'the cap or-box extension C', i .having a screwthreaded portion to be enbetween` the shoulder 2 of the axle and the gaged with the projection B5., The.cap or box extension has a pocket 4, which coacts with the end of the projection B3 to hold be- Y tween them a track D, shown as a ring. The

neck 'is surrounded by an end-thrustwasher E, having antih'iction means, shown as a series ot balls ein a ball-race cut in the face of the ring next the track D. The tenon has applied to ita nut F, shown as provided with a shoulder f, at one side of which is a neck f i", that receives over it a second end-thrust washer G, having antifriction devices, showny as a series of balls g, held in a ball-race made 'Q 7o the track D.V These balls contact with the track at its o posite sides and serve to resist` in that 'side of said end-thrust Washer next without shoc r the end-thrust strains that always exist to a greater or less extent in all bearings. contact with one side of the Washer E.

The inner end of nut F is made to I believe that I am the first to use a hub or box having a track restrained against longi tudinal movement therein, and to rovid'e for running against the opposite si es ofsaid track, it surrounding the tenon of the axle, I employ antifriction means supported through the axle at the outer end 'of t 1e hub or box. In my improvement hereint illustrated the track D atthe end of the box is shown as sustained in a pocket of the cap or box exten.- sion, and the innermost end-thrust washer of the pair, it surrounding the tenon ofthe axle, acts as a cage-controller against which the end of the usualroller-cage acts at intervals in its endwise-traveling movement.

Having described my invention, what I claim, and desire to secure by Letters Pate ent, isf 1. In a bearing, a hub or box, an axle having a tenon, a track disconnected from said axle, a pluralityoi" end-thrust washers surroundin said tenon at the outer end of the axle an disconnected from the hub or box,. [OO

.and balls interposed between said `washers and track'.

In a bearing, a hub or box, an axle have.

eacha groove, antitrictionmeans in said-,t` grooves, said antifrictionrneans contactingwith opposite sides of said track.

3. In a roller-bearing, a hub or box, 'ai trackv sustainedl by the hub or`box near itS outer end, an axle having a tenen-at its onces end, and two end-thrust wash eraV surrounding said tenon and pmvdcd U sides with zmnum grooves, means in smid grooves, sa means conta @ting normay j.' .1 sides of' said muck.
